Introduction The Model Context Protocol (MCP) is rapidly becoming a foundational layer for connecting AI models to external tools, data sources, and services in a standardized way. As more powerful capabilities are exposed to models—querying databases, sending emails, acting in SaaS systems—authorization becomes a central concern. This article walks through: What MCP is and how resources fit into its design What link resources are and why they matter How link resources are typically used to drive authorization flows Example patterns for building MCP servers that handle auth securely Best practices and common pitfalls The goal is to give you a solid mental model for how MCP authorization with link resources works in practice, so you can design safer, more capable integrations. ...

Introduction Tool calling (also called function calling or plugins) is the capability that turns large language models from text predictors into general-purpose controllers for software. Instead of only generating natural language, an LLM can: Decide when to call a tool (e.g., “get_weather”, “run_sql_query”) Decide which tool to call Construct arguments for that tool Use the result of the tool to continue its reasoning or response This post is a deep dive into the anatomy of tool calling: the moving parts, how they interact, what can go wrong, and how to design reliable systems on top of them. ...
